IMPROVEMENT IN MACHINES FOR ROLLING B LANKS, FOR CARRIAGE-AXLE CLIPS.

Specification forming part of Letters Patent No. 200,603, dated February26, 1878; application filed I December 26,1877.

To all whom t'tmay concern: 7

Be it known that we, EMEROUS D. OLAPP and FREDERICK VAN PATTEN, of thecity of Auburn, county of Cayuga, and State of New York, have inventedcertain new and useful Improvements in the Manufacture of Carriage- AxleClips; and we do hereby declare the following to be a full, clear, andexact description of the same, reference being had to the accompanyingdrawings, forming a part of this specification.

Heretofore carriage-axle clips have been made by dies, one of which wassecured in a drop-hammer and the other in an anvil, the two havingsuitable depressions andraised portions, to, give the proper form of theclip to the heated blank when placed between and subjected to theiraction. This method of manufacture was expensive, because the workmanhad to prepare a separate blank for each clip, thenplace it in the lowerdie on the anvil, then trip the drop, then wait for the upper die tostrike and recede, then remove the clip from the die, and, then removethe pins fprmed by the dies on the clip by trimmingdies, thus consumingtime and wasting material that ought to be saved, and because the diesthus used wore away rapidly, and had to be frequently replaced.

Efforts have been made to produce clips with greater rapidity and withless wear upon the dies by causing the latter to revolve instead of movein straight lines. In all cases, however, where this has been attempted,a separate blank for each clip had to be first prepared, and then, whenheated, fed to the revolving dies with extreme care and precision, thedifficulty in doing this successfully being very great, if notinsurmountable.

The object of our invention is to produce these clips without thenecessity of preparing and properly feeding a separate blank for eachclip with greater rapidity and economy than can be done with the oldmethods; and it consists in the means employed, as will be hereinnafterfully pointed out and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a pairof rolls for carrying out our invention, with their housings andadjusting means, a bar of metal being shown entering between the rollsand a series of U1\TITED STATES PATENT OFFICE.

Fig. 2 is an elevation of the rolls and their housings, the ends oftherolls being broken away where the power is applied to revolve them.Fig. 3 is a plan view of a series of clips asthey come from the rollsshown in Figs. 1 and 2. Fig. 4 is a plan view of oneof shown in Figs. 1and 2, enlarged. Fig. 8 is a plan view oftwo of a series, of clipsenlarged I as they come from the enlarged rolls.

A are housings, in which are journaled rolls.

B G, the lower one, .B, of which turns in bearings D in the housings A,and the upper one, 0, in boxes E in said housings. Screws F,

passing through bars G on top of the housings, and impinging upon theboxes, keep the rolls B and O in contact.

The housings, boxes, bearings, means of holding the rolls in contact,and means of driving them are of the common and well-known construction,form no part of our invention, and may be of any other suitableconstruction.

The roll B is provided with a-recess, H, ex-

tending around it, of a depth equal, or nearly.

equal, to the desired thickness of the flat I, and of a width equal, ornearly equal, to'the said fiat I of the clips to be produced. In thebottom of this recess are depressions 1 2 3-4, the depressions 1 2gradually increasing in width and depth until they meet the depressions34, which latter extend to and are partially separated by lips 5. Thedepressions 1 2 are the reverse in shape of the strengthening-ribs K ofthe clips which are to be formed in them.

The depressions 3 4 are of a width, at the parts where they meet thebottom of the recess H, equal, or nearly equal, to the diameter of theround or bolt ends L of the clips, and at the bottom are rounded thereverse of one-half of said ends L, and of a depth on a radial linedrawn from the center of. the roll B to its periphery, passing throughtheir bottom, equal, or nearly equal, to the diameter of said ends L.

clips issuing from them formed from said bar.

Thelip 5 serves to partially sever the con-" tiguous ends' Lof theclips, and marks the point at which they are to be completely severedwhen used.

g; The roll 0 is made cylindrical where it covers the recess H, and runsin contact with the roll B just beyond said recess. .!In the drawings wehave shown four sets of depressions, 1 2 3 4, and lips 5, at such dis-.tances apart that four clips may be formed at each revolution of theroll B.

In carrying out our invention we first pass fj'a heated billet of metalthrough reducingi-lrolls of the common construction, in order todiameter preferably in a plane, or nearly in a plane, atright angles tothe axis of the rolls in the recess H, and between the rolls B G,asshown in Fig. 1, and as the rolls revolve it is forced into thedepressions 1 2 3 4 and recess H inthe roll B by the roll 0, filling thedepressions, to form the strengthening? ribs K and part of the ends L ofthe'clip, and spreading out in the recess H to form the fiat I of theclip and the rounded ends, the clip 5 partially severing andmarking thepoint where the contiguous ends L are to be completely severed.

. As shown in the drawings, by means of the rolls B G four clips may beformed, each time they revolve, from the heated bar, and clips continueto be formed until the bar is used up. Another bar, properly reduced,can then be inserted, and clips again produced, as just described. Theclips, after issuing from the rolls, are joined together, and areseparated at the points M midway between the contiguous ends L. Theseends, as they come from the rolls, are slightlyflat on one side, and notentirely round. I

If found desirable or necessary, after the clips are severed these endsmay be rounded by a few strokes of a hammer, or under a d opming-diesare formed in the rolling.

The depressions 1 2 may be varied in shape from that shown in thedrawings, and extended to meet each other, so as to form a continuousstrengthening-rib, K, on the clip, as shown in Fig. 6.

The. iron bar from which the clips are formed may be round, if desired,and,if oval, may be introduced between the rolls, with its largestdiameter in a plane parallel, or nearly par: allel, with the axis of therolls, and yet clips may be produced therefrom properly.

The lip 5 may be omitted, if desired, though we prefer to use it as aconvenient means of partially severing and marking the point at whichthe contiguous clip'sare to be separ-' ated.

Although we have shown four sets of depressions, 1 2 3 4, in the recessH, it is to be understood that less or more than founsets of suchdepressions may be employed to carry out our invention.

By our invention carriage-axle clips can be produced with a great savingof labor and material and wear upon the operative parts.

Having thus described our invention and the merits it possesses, what weclaim as new, and desire to secure by Letters Patent, is-- 1. The rollB, provided with one or more sets of depressions,1 2 3 4, and with arecess, H, in combination with the roll 0, having a No fins .that haveto be removed by trim cylindrical smiace, substantially as described.

2. The roll B, having one or more sets of depressions, 1 2 3 4, and arecess, H, with means for forcing the metal therein, substantially asdescribed. 7 l

3. The combination of a pair of rolls one of which is provided with arecess, H, two or more sets of depressions, 1 2 3 4, and one or morelips, substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
